Trivia

On page 1 frame 1 (A1), the map of Peru is incomplete. The northern part of Peru is shown as part of Ecuador. Ecuador had made claims to this part of Peru, and the map Hergé used for reference must have been one published by Ecuador, not Peru. [EC]

On page 15, Tintin's jump defies the laws of physics: if you jump off of a moving object, you will keep on moving forward until you land. Jumping off the moving train from where he was, Tintin should have landed farther--and crashed into the mountain. [EC]

Pages 58 and 59 show a northern hemisphere solar eclipse instead of a southern hemisphere eclipse. The eclipse shown in the Tintin magazine version of the story is correct. [EC]
